Read full description

"How many minutes until it gets dark?" Eliminate that anxiety from your hike. Sunset Hiker is a hiking watch app that automatically calculates accurate sunset times and remaining daylight based on your GPS location—even deep in the mountains with no signal. The "time remaining until sunset" is visualized in color on the clock face, allowing you to instantly judge when to descend and manage your pace. 【Key Features】  ■ Beautiful Design: A glass-like, transparent UI designed not to obstruct the breathtaking mountain scenery. ■ Intuitive Visibility: Color coding allows you to grasp the remaining time until sunset at a glance. ■ Advanced Calculation: Automatically calculates accurate sunset times based on GPS location—fully functional even offline. 【A Message from the Developer】  Have you ever been surprised by how quickly the sun sets in the mountains? That sudden moment of anxiety during a hike: "How many minutes until it gets dark?" I developed this app to eliminate that worry. I hope this app becomes a trusted partner for your safe hiking adventures. 【Important Notes】  *Sunset times are calculated based on your current latitude, longitude, and date. Please note that terrain features such as mountain shadows are not taken into account. Always plan with a margin of safety.
